Matador is made from HyprLyte Nylon.
At less than 90 microns thick, this hi-tech fabric is designed to maximize portability without sacrificing durability.

It seems to be more about having something to sit or lie on than something for warmth. If you did need to wrap it around you, I would guess it functions like a very light windbreaker jacket: keeps you "warm" by blocking the breeze.

And Cory, being a Canadian living in the UK, should be particularly aware of this kind of thing. I'm guessing they don't offer international orders because offering tracking for international orders would cost too much money, but at the same time - why not offer it any way?

Seems like they should make it in a much larger size to be used as quick shelter/tarp. when I go backpacking I don't carry a tent anymore, just a lightweight tarp that easily covers all my gear and keeps me as dry as in a tent. I was hoping this 'blanket' would be an improvement, but the sizes they offer aren't big enough for a tarp.

It reminds me of some sheet-like things my parents had 40 years ago. They were very, very thin--if you put one over your head you would still have acceptable vision. Very light, very compact and they provided an amazing amount of warmth if you wrapped them around you.

If you need a super-compact blanket that keeps you warm you can always get one of those foil emergency thermal blankets, but they're not much good for a comfortable night's sleep. I used one on a backpacking trip once when my sleeping bag proved insufficient for the cold nights; it did its job but it made crinkly sounds at the slightest movement.
